What is it I have to give reasons for?
I think the answer is false!
In a food web a lot of energy is
dispersed into the environment as heat energy. Food web is tool for
representing the feeding relationships among species within an ecological
community. In a food web at each tropic level, certain amount of energy is
driven away as heat as the organisms undergo cellular respiration.
Answer:
Taxol induces the assembly of microtubules, while Nocodazole suppresses tubulin assembly
Explanation:
Taxol and nocodazole are antimitotic drugs, i.e., drugs that inhibit the progression through the cell cycle, which is useful for killing cancer cells. Microtubules are proteins that act as the 'skeleton of the cell', which need to be reorganized when cells replicate. These structures (microtubules) are composed of α and β-tubulin heterodimers which assemble into protofilaments of microtubules. Taxol is an antimitotic drug that induces the formation of microtubules, thereby inhibiting microtubules' reorganization during mitosis. In consequence, cells treated with Taxol enter into apoptosis (i.e., programmed cell death). Moreover, Nocodazole is known to induce microtubule disassembly by interfering with the polymerization of tubulin monomers. In consequence, Nocodazole is useful to depolymerize the microtubule cytoskeleton.
